I remember walking the cobblestone bridge across Hue’s Perfume River and this stopped me dead in my tracks. Look at this woman, how she squats over the edge of the dock to scrub the dirty clothes. I must have stood there for at least 10 minutes, jaw dropped. How could she stay balanced? How did she not fall? She must have stronger quadriceps than an Olympic hurdler! A couple years on, whenever I finish what I think is a brutal lower-body work-out with my legs and hip flexors screaming, the image of the woman and her laundry float into my mind, reminding me that a good lower body work-out is always relative.
